ABSTRACT:
To provide a concentration measuring method which enables a stable and highly accurate concentration measurement while avoiding the step of making a background measurement.The concentration measuring apparatus includes: a concentration measuring contact that is brought into contact with a subject of measurement; a light source that emits light and enters the light into the concentration measuring contact; a polarizer that takes out p-polarized and s-polarized light components from the light which is passed through the concentration measuring contact into the subject of measurement, transmitted in the subject of measurement, and returned to the concentration measuring contact; a photodetector that determines at least the quantities of the p-polarized and s-polarized light components taken out by the polarizer; and calculating means that calculates the concentration of a specific component contained in the subject of measurement based on the determined results.
